Sky Sports understands that Middlesbrough starlet Bryn Morris is being targeted by Manchester United, Manchester City, Chelsea and Liverpool.
The 16-year-old, who is widely regarded in England as one of the best players of his generation, can play in midfield or defence.
Morris is already a key figure in Kenny Swain's England Under-16 side and is also the captain.
The Teesside-born youngster is seen as one of the gems of Boro's highly acclaimed youth academy.
Boro already recognise Morris's talents and included him in their FA Youth Cup squad, despite his tender years.
But Morris, who has just returned to the country after leading England to third in the Montaigu Tournament in France, is attracting strong interest following a string of impressive displays for the international side.
Whilst Boro's proud record of bringing through players means they hope any player will recognise the chances available to them at the club, they are fearful Morris could be lured away.
Sky Sports understands that England's top clubs are now on Morris's trail including Manchester United, Manchester City, Chelsea and Liverpool.
Morris cannot sign a professional deal because of his age, meaning Boro would only be due a compensation deal if he were to leave the club.
Boro remain hopeful that Morris sees his long-term future at The Riverside.
